&lt;!-- THREE STEPS TO INSTALL THREE TRIES:

   1.  Put the first code into the HEAD of your HTML document
   2.  Change protectedpage.html to your protected page
   3.  Add the final code to the BODY of your HTML document  --&gt;

&lt;!-- STEP ONE: Copy this code into the BODY of your HTML document  --&gt;

&lt;HEAD&gt;

&lt;SCRIPT LANGUAGE="JavaScript"&gt;

&lt;! &gt;
&lt;! &gt;

&lt;!-- Begin
function password() {
var testV = 1;
var pass1 = prompt('Please Enter Your Password','');
while (testV &lt; 3) {
if (!pass1) 
history.go(-1);
if (pass1 == "password") {
alert('You Got it Right!');

&lt;!-- STEP TWO: Change protectedpage.html to your protected page  --&gt;

//  Change the following URL to your protected filename

window.open('protectedpage.html');
break;
} 
testV+=1;
var pass1 = 
prompt('Access Denied - Password Incorrect, Please Try Again.','Password');
}

history.go(-1);
return " ";
}
// End --&gt;
&lt;/SCRIPT&gt;
&lt;/head&gt;

&lt;!-- STEP THREE: Copy the last code into the BODY of your HTML document  --&gt;
